Investors put $29M into Solana privacy engines. Users put about $2M into the privacy apps. That 14x gap is the clearest open lane in Solana privacy. Follow the money, then the users, then the partners a founder needs. Where did the money go? Into the lower layer. Three engines run sealed math for other teams: > @Arcium: MPC across many nodes. Mainnet alpha since Feb, $9M raised. > @magicblock: Private Ephemeral Rollups in secure hardware. $10.5M raised, Private Payments API in mainnet beta since March. > @inconetwork: encrypted compute, in beta on Solana devnet. $9.5M raised across two rounds. Where are the users today? Deposits sit with a handful of consumer apps. One side of the gap is funding and the other is deposits, so read 14x as a direction: > @theprivacycash: the top Solana privacy pool on DefiLlama. $1.62M TVL, $135K in 30-day fees. > @UmbraPrivacy: private hold, send and swap. v2 live since Oct 13, $0.35M TVL. > @cloak_ag: private payroll and payment links. Mainnet since Sep 15. > @looftapay: private USDC to a social handle, live with MagicBlock privacy. Wallets that want privacy through an API have an option too: @helius: Solana Rings, encrypted balances your app calls through an API. Beta on devnet. The money sits one layer below the users. So the engines need apps, and some already have them.
